Recent highlights from BABAR
Dr. Wolfgang Gradl (Inst. für Kernphysik)


After more than eight years of successful operation, the BABAR experiment at the PEP-II B-factory at the SLAC National Accelerator Laboratory ceased data taking in April 2008. The last three months of data taking were devoted to running on the Upsilon(3S) and Upsilon(2S) resonances, collecting about 100 Million decays of each resonance.

In this talk, I will present a selection of recent results from the core BABAR physics programme, including an updated measurement of sin(2beta), the parameter describing CP violation in the B system, and the first observation of the eta_b, the ground state of the bottomonium system.
